DOSE-INDICATOR.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed April 15,1914. Serial N0. 832,062.

To ad whom it may concern Be it known that we, JOHN S. DUNN and CARL A. llmss, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Dose-Indicators, of which the following is a specification.

This invention relates to indicators, and more particularly to a device for indicating the periods at which medicines are to be taken, and it is one aim of the invention to so construct the device that there will be little or no liability of a mistake being made, and to further so construct the same that the time at which the rst dose was taken will' be permanently indicated.

Another aim of the invention is to so construct the device that it may be employed when two or more different kinds of medicines are to be taken, either at corresponding or different intervals.

In the accompanying drawings: Figure l is a plan view of the indicator embodying the present invention. Fig. 2 is a vertical transverse sectional view therethrough. Fig. 3 is a perspective view of one of the markers employed in connection with the indicator.

In the drawings, the indicator is illustrated as including two disks, one of which is indicated by the numeral l and the other by the numeral 2. The disk l constitutes the time indicating disk and the disk 2 is the interval indicating disk, the disks being connected for relative turning movement aXially by means of a rivet 3, or any other similar fastening element. The disk l is divided in substantially the same manner as a clock face, that is to say, into hours and fractions of hours, radial lines 4f being preferably marked upon the face of the disk and eX- tending from the margin of the disk inwardly to or adjacent to the margin of the disk 2. These radial lines divide the disk l into hours and quarter hours, and it is preferable that a circle 5 be marked upon the face of the said disk concentric to its periphery and adjacent thereto, and that this circle be divided by short dashes 6, which indicate five minute intervals, two of such dashes being, of course, disposed between each two of the lines 4. The disk 2 is provided at its periphery with a pointer 7, which is preferably substantially triangular and which is arranged to have its apex brought into registration with the radial lines 4: and dashes 6, as the disk 2 is rotated upon the pivot 3. It is preferable that the face of the pointer portion 7 be of a distinctive color, so that its location with relation to the lines e and dashes G may be readily noted.

The face of the disk 2 is divided by a number of radial lines 8, one of which lines, indicated specifically by the numeral Sa, eX- tends medially of the pointer 7. |There are preferably twelve of the lines S and, therefore, the disk 2 may be rotated to position with these lines coextensive with the lines 4 which are located at the hour periods and which are suitably designated, as at 9, upon the face of the disk l. The face of the disk 2 is further divided by radial lines l0 which, when the disk 2 is in the position above stated, are coextensive with the lines l of the disk l which indicate quarter hours. The lines et are referred to above as indicating hour and quarter hours, but it will be obvious that certain of these lines may be considered as indicating half-hour periods. Consequently, when the disk 2 is in position with its lines 8 coeXtensive with the lines e designating hour periods, certain of the lines 10, indicated specifically by the numeral 10a, will be coextensive with these lines 4C which designate the half-hour periods. The face of the disk 2 is further divided by a number of concentric circles 1l which are, of course, intersected by the lines 8, l0 and 10a, and at the points of intersection of each of the lines 8 and 102l with the outermost one of the circles 1l, there is printed or otherwise marked the fraction 95. In like manner the numeral l is printed or otherwise marked at the points of intersection of each of the lines 8 with another one of the circles ll. Similarly, the points of intersection of certain of the lines 8 and l0a with another of the circles ll are indicated by the numeral 13.-, as indicated at le. Furthermore, the points of intersection of the lines 8 or certain of these lines, as the case may be, with others of the circles 1l, are indicated by the numerals 2, 3, 4, G. Now, assuming that the lines 8, l0 and 10"- indicate respectively hour and Quarter-hour and half-hour divisions, it will be observed that the fraction J,- occurs at intervals of one half hour upon the disk 2; that the numeral 1 occurs at hour intervals upon the disk; that the numerals l-L occurs at an hour and one half intervals, and so forth.

A11 arm 15 is pivotally supported against the under side of the disk 1, by means of the rivet 3, and this arm at its outer end is overturned about the periphery of the disk to form a pointer 16, which preferably has printed or otherwise marked upon its face Start The point of the pointer 16 is so positioned that in the angular movement of the arm 15 this point will travel along the circle 5 and may consequently be brought into registration with any of the radial lines 4 or dashes 6. In addition to the arm 15 and its pointer, there are provided one or several of the pointers shown in Fig. 3, each of which includes a back portion 17 and a finger 18, the material from which the pointer is formed being bent between the back and finger so as to engage over the edge of the disk 1, in the manner illustrated in Fig. 1 of the drawings. It is preferable that the pointer shown in Fig. 3 be formed from resilient sheet metal and that its linger be slightly sprung toward its back so that the pointer will be frictionally held at any point to which it maybe adjusted about the periphery of the said disk 1.

Assuming that but one kind of medicine is `to be taken, and that the iirst dose is taken at two oclock and the other doses are to be taken at two hour intervals thereafter, the arm 15 is swung until the pointer 16 registers with the` line 4 which coincides with the hour designation 2 upon the disk 1, and the disk 2 is then rotated until its pointer 7 also registers with this line. In determining the time at which subsequent doses are to be taken, it is only necessary to follow that one of the circles 11 within which the numerals 2 are printed, and it will be found that the'radial lines which intersect the said circle at the points of location of the numerals will be coeXtensive with the lines t designating the hours #1, 6, 8, 10 and 12, which are the hours at which the said subsequent doses are to be taken.

The foregoing is but a simple example of the use of the device, and it will be apparent that should the first dose be taken five minutes after two, the period at which the subsequent doses should be taken may be determined with equal facility and without the necessity of calculating. Should it be necessary to give two or more kinds of medicines, one or more of the pointers shown in Fig. 3 will be employed and placed at intervals about the periphery of the disk 1 to indicate the time at which the rst dose of each kind of medicine was taken. The arm 15 will of course remain at its position of Vadjustment and the disk 2 may be rotated independently of this arm, so as to bring its pointer opposite any one of the pointers 18 to ascertain the time at which each different kind of medicine is to be taken. y

It is to be observed that the line 8a has arranged along it, at its point of intersection with the various circles 11, one of each of the fractions or numerals occuring upon the face of the disk 2, so that this line constitutes a base from which all of the various intervals are properly relatively spaced in their respective series.
